Connecting The Switches To Form The Stack Ring - Extreme Networks Summit X150 Series Hardware Installation Manual

Connecting the Switches to Form the Stack Ring

After you have installed the individual Summit switches, connect the switches together using the
stacking cables.
The examples in this section show cable connections and the recommended order for connecting ports
to facilitate the easy setup configuration.
In general, it is best to connect Stack Port 2 on one switch to Stack Port 1 on the switch with the next
higher slot number. Although you can connect the switches in any order, connecting them as shown in
these examples will produce better predictability and easier software configuration. It is essential to
create an unbroken data path through all the switches in the stack.
Note
The connection recommendations in this section do not apply to Summit X650 series
switches with installed VIM1-SummitStack512 modules. For information about connecting the
ports on the VIM1-SummitStack512 modules, see
For instructions to connect specific types of stacking cables, see
Using SummitStack Ports and 40G Stacking Cables
SummitStack ports are integrated into the back panel of the Summit X250e, X440, X450, X450a, and
X450e series switches.
In addition, the X460, X480, and X650 series switches accommodate VIMs or stacking modules that
provide SummitStack ports. The Summit X770 can be stacked using QSFP+ front panel ports.
The examples in the following sections show various physical stacking arrangements: all switches in a
single rack, switches in two adjacent racks, and switches at the tops of several racks in a row.
Single-Rack Stacking Configurations
These examples show stacks of either four or eight switches in a single rack.
The slot numbers presume a console connection to the switch at the top of the physical stack.
The following figure shows cable connections for a 4-node stack using SummitStack 40G cables to
connect switches with integrated SummitStack ports.
